Well, I do believe that is the intention to break up the fanbases in order to write compelling stories using characters needed to play them out, however, I still contend that the choice of moving Sami to headliner, was poor. She wasn't ready, her fan base wasn't ready and the storyline isn't compelling or believable.

It turned out to be a double-edged sword, too. Instead of breaking up Lumi's fan base, it's created a new fan base.

To me, the best way to break up a fan base is to move the characters off screen or off the show and if they want to use one, just bring back a single person. Point in view, Jack without Jen. There is no reason on earth not to bring Jack back without Jen in my opinion.
